At what displacement is the `KE` of a particle performing `SHM` of amplitude `10cm` is three times its `PE`?

A

`2.5cm`

B

`5cm`

C

`7.5 cm`

D

`10cm`

Text Solution

Verified by Experts

The correct Answer is:
B
`K.E. = 3.P.E.`
`P.E. = (1)/(2) m omega^(2)x^(2), K.E. =(1)/(2) m omega^(2) (A^(2)-x^(2))`
